COMBINED BED-SPRIN G FRAME AND IBEDSTEAD.

Specification of Letters Patent.

Patented Dec. 27, 1921.

Application filed July 16, 1920. Serial No. 396,686.

To all whom it may concern:

Be it known that I, HARRY LrrvAK, subject of the Government of Russia, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Combined Bed-Spring Frames and Bedsteads, of which the following is a specification.

This invention relates to combined bed spring frames and bedsteads.

One of the objects of this invention is the provision of a combined spring frame and bed stead which is collapsible for convenient folding into a comparatively small space, and which is simple in construction and cheap to manufacture.

A further object of this invention is the provision of a bed spring frame adjustable longitudinally for maintaining the proper tension on the bed spring and for eliminating the sag therefrom.

Another object of this invention is the provision of a bed spring frame adapted for use in connection with a foldable adjustable bed spring. 7

Other objects of this invention will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which. the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of various possible illustrative embodiments of this invention,

' Figure 1 is a top View of my improved frame as it appears in use in connection with. foldable spring.

Fig. 2 is a side view of the same showing the legs in operative position in which the frame may be used as a bed stead.

Fig. 3 is a vertical, section of the same on line 3-3 of Fig. 1;

Fig. at is a detailed vertical section on an enlarged scale of the means for adjusting the length of the frame;

Fig. 5 is a side view, enlarged, of one of the elements making up the central part of the frame side;

Fig. 6 is an end view of the same; and

. central part of the frame sides.

Fig. 'Tis a front view in partial section of the end rails of the spring frame in a partly folded position.

In the practical embodiment of my invention shown in the drawing, each of the end rails of the bed spring frame is seen to comprise a pair of channel members 10 and 11 arranged with the web backs thereof uppermost, and hinged together 011 their un derside by means of a hinge as 12. Suitable slidable bolts 13 operating and yieldingly held in bolt supports 1 1 serve to maintain the hinged members 10 and 11 in their extended position as will be readily understood from the drawing (Fig. 1). For detachably holding the outer ends of the auxiliary coil springs 15 of the type in general use in the ends of bed spring frames to the end rails, suitable holes 16 are provided at intervals along members 10 and 11, the other ends of said springs 15 being secured to cross members 17 of the bed spring sections. The outer ends of the springs 15 are suitably shaped to be readily inserted into and removed from holes 16.

At the underside of the extremity of each of the members 10 and 11, a short projecting channel arm 18 is suitably secured substan tially at right angles thereto, said arm 18 being preferably closed at the outer end 19 (Fig. 4), a rib 20 being desirable as shown to reinforce and strengthen the oint. Each of the other members 10 and 11 is in like manner secured to projecting channel arms 21, similar to arms 18 but preferably made longer than the latter as shown, the arms 21 being designedto reach nearly to the Ribs 245 are provided to act as braces for said arms 21. Corresponding to arms 21 and adjust- ,ably connected to arms 18 as by turn-buckles 22 are side channel portions 23 extending centrally approximately the same distance as arms 21, and connected to said ,arms by means of centrally located members 25, as will be more fully described hereinafter.

The turn buckle supports 26, 27 are suitably secured in members 18 and 23 respectively and serve respectively to hold screw bolts 28 and 29 immovably therein, one of said bolts having a right hand thread and the other a left hand thread cut thereon. It will be seen that rotation of turn buckle 22 in one direction draws parts 18 and 23 together while the rotation of said turn buckle in the opposite direction forces said parts 18 and 23 apart. The central connecting member 25 comprises a main outer channel section held with the web back uppermost a pair of strips fastened to the sides of the webs and a similar channel section 31 serving to support and to hold said strips more securely in place. Said strips 30 are spaced to engage the inside of the flangesof portions 23 and 21 with a slight spring action so that members 25 may be held in place even before turn buckles 22 are manipulated to put pressure thereon. As will be readily understood, when compressive stress is put on members 25 through members 23, central members 25 will be securely retained in place without danger of falling-out when weight is put thereon.

The bed spring which is preferably used in connection with my improved frame comprises two parts 32 and 33 each having suitable outer cross members 17 and inner cross members 34. The outer cross members are detachably secured to the frame members 10 and 11 by springs 15 as heretofore described,

while the inner cross members 3 1- are adjustably held together as by means of turn buckles 35 operating on screws 36 secured in said cross members. A suitable plate 37 hingedly secured at 38 to one of members 34 covers said turn buckles 35 and serves to bridge the gap between said members 34: in the operative position of the. bed spring. Foldable legs 39 are pivoted on the outside of arms 18' while similar legs 40 are pivoted between the downwardly extending: flanges of arms 21 so that legs 40 fold in between said flanges, and are held by a suitable pin 41, while legs 39 fold about their pivots on the outer side of the outer flanges of arms 18, being held by a suitable pin 42. It will readily be seen that the frame may be used as a bed stead when legs 39 and it) are unfolded into their upright position, and that said frame may be used merely as a spring frame when said legs are folded in.

When it isdesired to fold up the frame,

springs 15 are detached from holes 16, the

detaching operation being made easier if turn buckles 35 are, firstfmanipulated to ease the pull on said spring. The spring sections 32 and 33 may then be folded one onthe other or they may be entirely detached from each otherby removing turn buckles35 therefrom. The bed spring having been detached from the frame the pres sure on central section 25 is thereby removed and said section can then be easily pushed down strips 30 moving down along the inside of the downwardly projecting flanges of the channel members 23 and 21.. Bolts 13 are then slid back out of engagement with theboltsupports 14:. on members 11, and said members 10 and 11 folded about hinges 12 (Fig. 7). To set up the frame, members 10 and 11 are first unfolded, bolts 14 shot, the ends of springs 15 inserted in holes 16, central members 25 arranged in position and turn buckles 35 and 22 properly manipulated.

Besides their use in the setting up and in the collapsing of the spring frame, the turn buckles are designed in addition to vary the tension or pull of the bed spring as desired to give the correct amount of resiliency thereto, and to eliminate the sag which always develops to a greater or less extent in bed springs after long continued use.

As various other possible embodiments .might be made of the. above invention and well adapted to meet the most severe conditions of hard practical use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1; In a collapsible bed spring frame,

hinged end rails and sides comprising a proj ecting arm secured to said end rails, a side member ad ustably connected to one of said arms, and a detachable section arranged to connect said side member with the other of said arms.

2. In a collapsible bed spring frame, hinged end rails, means for holding the end rails in extended position, collapsible side sections each comprising an arm'secured to said end rails, a side member adjustably connected to one of said arms, and a detachable section arranged to connect said side member with the other of said arms, and means carried by said sections for adjusting thelength of said frame.

3. A collapsible bed spring frame comprising hinged end rails, means for holding said rails in extended position, side sections each comprising a projecting arm secured to said end rails, and detachable side sections spaced from and adjustably held to one of said arms, and a central connecting portion having prongs thereon for engaging the other of said arms and said detachable side section.

a. A collapsible bed spring frame comprising hinged .end rails, means for locking said rails in extended position, side sections each comprising a projecting arm secured to said end rails, and detachable side secportion having prongs thereon ior frictionally engaging the other of said arms and said detachable side sections.

5. A collapsible bed spring frame comprising hinged end rails, means for holding said rails in extended position, side sections each comprising a projecting arm secured to said end rails, detachable side sections spaced from and adjust-ably held to one of 10 said arms, a central connecting portion having prongs thereon for engaging the other of said arms and said detachable side section, and means for adjusting said detachable side portion relative to one of said arms.

Signed at New York city, in the county of New York and State of New York this 23rd day of June A. D. 1920.
